The Bookshelf Stuffers are a series of 12 short supplements designed to be universally compatible with any fantasy role playing game system written by David Woodrum. They were originally published by Top Fashion Games and still inside each PDF is a link to a defunct website. They are now published by Dark Quest Games.
All the volumes are available separately, but some are also available in various bundles. There doesn't appear to be a single bundle that contains all 12 volumes though. TFG Bookshelf Stuffers Bundle 1 contains volumes 1-10, but the other bundles that these are included in also included other products too. The supplements are only available as PDFs.
The aim of the supplements is that, should players pick up a random book from a bookcase or anywhere else, then it is possible to describe the book in rather more detail than simply describing it as a book. This can add more depth to an otherwise generic setting, and help satisfy players' curiosity. Each supplement contains 20 books in total.
The first part of generating a book is a table. This is divided into Roll, which is a simple 1-20 roll achieved with a 20 sided die in order to select a book, Book Title, the rolled book's title, Author - in later volumes, in earlier ones the author's name tends to be just in the description, Race/Cultural/Language, the exact selection varies in different supplements, which defines what cultures the book is likely to be found in and Value, or how much the book is worth, usually in gold pieces.
The next section goes through and individually describes each book from the table. These can be quite short descriptions, being only a line or two, or up to a couple of paragraphs or more. These can give the contents of the book, its size in pages, an analysis of how useful or rare the book is and its physical appearance.
The polish of the supplements generally improves as the series progresses. The twelve volumes in the series are as follows:
Volume 1: A Little Bit of Everything
The first in the series contain, as the name states, books on a variety of topics. This is essentially a collection without a theme.
Volume 2: Wicked
A collection of books by wicked and vile individuals.
Volume 3: Bardic Favorites
This is probably the poorest of the set, as each book's description is limited to how many different songs, ballads etc. or included in the volume and what they are about. This is only slightly more than one line in most cases.
Volume 4: Kitchen Collection
This details books of recipes, from the fairly simple to the disgusting. The recipes are not actually included.
Volume 5: Arcane Library
This is a collection of books that could be found in the library of a magic-user.
Volume 6: Craftsmens' Guides
The descriptions of the books in this volume vary quite a bit in length, and cover various crafting subjects.
Volume 7: Nature Guides
Another collection with fairly short descriptions, often only one sentence, with nature as a theme.
Volume 8: Bejewled Enchantments
This is based around using gemstones in magic. The descriptions in this volume are some of the longest in the series.
Similar in some ways to Volume 2, this again contains books with descriptions of a decent length.
Volume 10: Assorted Selections
Like Volume 1, this covers an assortment of topics, with lengthy descriptions of the books.
Volume 11: Massive
The books described in this volume again cover an assortment of topics, but the books themselves are described as being quite large or lengthy. The descriptions are also substantial.
Volume 12: Midnight Reads
The final volume covers topics associated with the night.
The actual format of the layout of each individual volume varies, although how they are arranged with regards to using the subject matter is very similar. In some, the main PDF includes the front cover, in others the cover is either a separate PDF file or it's a separate image.
When combined the Bookshelf Stuffers series make a useful addition to any Game Master's toolkit. It is easy to generate a total of 240 books and give decent descriptions of what has been found, should the characters suddenly decide to start randomly pulling books off shelves.
There are other resources available that go into both more and less detail than these do. Those with the lowest level of detail are usually just random book generators that cover little detail beyond the generated book's topic and value. Those that go into more detail may actually provide some of the text of the book. The Bookshelf Stuffer series is an inexpensive way of quickly adding more depth to a game, and the books themselves could also be used to help characters learn in-game skills for example.
