General Help and Explanations
- Data Sources and Collection Methods
All book data are retrieved from Amazon.com using the Amazon E-Commerce Service (ECS) Application Programming Interface.
Except for relatively static data (such as title and author) book data are normally retrieved twice a day,
so dynamic data such as sales rank, price, customer rating, number of reviews, and used-book data are generally recent.
To see the exact timestamp of the request that produced the book's dynamic
data, view the book's details section (click the 'Details' link in the
middle column). The request timestamp is the last detail item
displayed.
The Amazon E-Commerce Service is imperfect and sometimes returns inaccurate data.
In general, we depend on outside sources for the data used to generate this web site so we cannot guarantee
the data's completeness or accuracy.

- Amazon Sales Rank
Amazon's proprietary measurement of how well an item is selling at
Amazon relative to other items in the same product line. (Examples of
product lines include Books, DVDs, Electronics, etc.) A sales rank of
'1' is applied to the best-selling item in a product line.
VeryWellSaid.com
only tracks book sales, so sales ranks (and sales rank gains and
losses) are directly comparable across book-topic categories.
Sales Ranks for many best-selling items change on an hourly basis.
Click on the column's Up or Down arrow to sort by sales rank.

- Average Customer Rating
The average of all Amazon customer ratings of the book to date. The
possible rating values are integers from 1 (star) to 5 (stars); 1 is
the lowest rating. The book's detail section (to see the detail
section, click on the 'Detail' link in the main column) includes the
number of reviews from which the average rating was calculated.
(Average Ratings derived from fewer than 5 reviews show the superscript
'1'.)
Click on the column's Up or Down arrow to sort by customer rating.

- Category
VeryWellSaid.com tracks the sales rank of top-selling books in
many highly focused content categories that are of particular
interest to our readers, as well as in 29 broad Amazon topic categories.
Custom topic categories.
VeryWellSaid.com tracks top sellers in many highly focused content categories
and new categories are added every week. Generally, the more focused the topic,
the more useful it is for prospective book buyers or people otherwise interested in the topic.
Though imprecise, such categorization schemes allow people interested in a topic
to find relevant books very quickly.
Amazon topic categories. Amazon categorizes books into broad content categories.
These categories are hierarchical and a top-level category is comprised of many descendent categories. (A
list of the top-level Amazon.com (USA) topic categories, and all their
descendent sub-categories, can be found here
.)
VeryWellSaid.com. currently tracks top-selling books in 29 broad top-level Amazon content categories (e.g., Cooking, Medicine, Sports, etc.).
Note that the books in a category (either an Amazon category or a custom category) are not exclusive to that category:
a given book may be included in many different categories.
For example, a biography of a business leader may
be included in the Biographies & Memoirs category and the Business
category, as well as in other categories.
An alphabetical list of all top-seller categories at VeryWellSaid.com is available
here.

- Read Customer Reviews
The number in the "Read Reviews" column on any of the main topic pages
is the total number of customer reviews for that book to date: it links
to a reviews page which displays the most recent fifty Amazon.com
customer reviews for that book. These are the same customer reviews
which you can read on the Amazon.com web site, but more are displayed
per page.
On the reviews page you can page through all of the
customer reviews for a book, fifty per page and newest to oldest, by
clicking "Next" or "Prev", or you can change the sort type and
direction and page through the reviews sorted by customer rating, the
number of people who found that review helpful, or by review date.
On the reviews page you can hide the reviews
themselves and view only the review summary data (that is, the review
title, book rating, and the number of people who found the review
helpful) by clicking "Show Summaries Only". Clicking "Show Full
Reviews" displays the full reviews in addition to the summary data.
VeryWellSaid attempts to publish new customer reviews
of a book within a day after the new reviews appear on the Amazon.com
website. (With respect to the older reviews, the only data that can
potentially change on a daily basis is the "Number of People Who found
This Review Helpful" and these data are updated every weekend.) Each
review displays a last-updated timestamp at the end of the review.
Due to the large volume of review data and multiple
data-update methods used, there will often be discrepancies between a
book's total-review-counts, as they are variously displayed on the main
topic page in the "Read Reviews" column, or in the book summary section
at the top of each reviews page, or in the navigation section of the
reviews page.

- Sales Rank Gain or Loss
The most-recently retrieved sales rank of a book is compared to its
past sales rank (if available), over a number of periods. A sales rank
gain is displayed in blue with a positive sign. A sales rank loss is
displayed in red with a negative sign. For example, a book with a
current sales rank of 10, that yesterday had a sales rank of 100, has a
1-Day sales rank change of + 90 (sales improved). SalesRank data is
normally retrieved twice a day.
Sales rank data are continuously tracked for a wide
range of books in each category, including especially less popular
books, to insure that sales change data will be available for
comparison when less popular books quickly become best sellers.
Click on the 1-Day, 7-Day, or 30-Day sales rank change columns' Up or Down arrows to sort by the respective sales rank changes.

- Search This Page Only
Search This Page Only only searches for books on the current best-seller page, not on the entire site. (To search
all of VerywellSaid.com, use the Google™Site Search Box immediately above Search This Page Only.)
As you type in the search box, the number of matches in the specified
book-description category (Titles, Authors, ISBNs, or all three--as
specified in the Page Search Options) are displayed beneath the search
box. Enter ISBNs without spaces or dashes. Clicking 'Search' highlights
the rows (in red) in which the match was found. The matched term will also be
highlighted (in yellow) inside the book details section of the row. Searches are not case-sensitive, only the current
page is searched, and terms are matched wherever they are found
embedded in the target category's text. (The text doesn't have to start
with the search term.)
Each time you click 'Search' the page is first reset to normal by clearing any prior searches\highlighting,
and then only the rows (if any) matching the current search term are highlighted.
Clicking 'Reset' resets the page to normal and clears the search box.
Click 'Show Page Search Options' to show the search options.
Search Options
- You can search Titles, Authors, ISBNs, or all three.
- If 'Show Details' is checked, the detail section of matching rows will be displayed.
- If 'Go to First Match' is checked, the browser will jump to the first matching row.
- If
'Hide All Details First' is checked, the browser will also close any
detail sections you opened manually, independently of searching, before
it highlights matched rows on 'Search' or resets highlighted rows on
'Reset'.
- If,
after clicking 'Search', you then change the search category
(e.g., from 'Titles' to 'Authors'), the page will be reset, but you
will still need to click 'Search' again to see the rows in which matching
Authors were found.
Note: Search This Page Only is not created by, nor in any way affiliated with,
Google™, even though the Google™ Site Search Box is immediately above it.

- Subscribe to Pages at VeryWellSaid.com
A RSS Syndication Feed (or "channel") allows a web site publisher to
automatically distribute frequently updated content such that feed subscribers
do not need to visit the web site directly in order to read it. Rather, subscribers
can read the syndicated content in a preferred or alternate format, either with special programs called "feed readers" (such as "FeedDemon"),
or via browser-based online feed-aggregation services (such as Google Reader, Bloglines.com or My.Yahoo.com), or
or even directly in browsers by navigating to the feed address.
For example, you can use your browser to view directly the feed for the The Top-Selling Influenza Books by
clicking here.
(Note that feeds are primarily designed to be read by machines:
though web browsers can typically display the feed information, some browsers will format the information much better than others.)
You can always view a VeryWellSaid.com RSS feed directly in your web browser--and obtain the url of the page's feed--by clicking the
"XML" text link in the series of links following "Subscribe[?]".
VeryWellSaid.com publishes five feeds for each of its top-selling book categories:
Top-Sellers, Highest-Rated Top-Sellers, Biggest 1-Day Sales Gainers in Top-Sellers,
Biggest 7-Day Sales Gainers in Top-Sellers, and Biggest 30-Day Sales Gainers in Top-Sellers.
An alphabetical list of all top-seller categories, including the urls of their feeds, is available
here.
