Not the Aurora's Catalogue, of course, but as a basic list of common items for quasi-medieval RPG, well rounded. Has some strange stuff (such as mules being significantly slower than donkeys and weigh half a ton), and shortcomings in form (tack/harness entries has text, but no tables), but in general not bad.

This PDF is 9 pages (8 are the content).

A pretty good list of items, etc, your characters will find useful: Beasts, tack, training, clothing, containers, carts, wagons, wheelbarrows, food, lighting, weapons, and other useful things.

As I said above, 8 pages are the content, which includes the index of contents. So that leaves 7 pages of useful items (and most are useful). The items are listed in triple columns per page, and are also listed clearly. A very useful list.

Did I forget to mention it's free?
