Ever since it began the JRA has been collecting books and welcoming donations from members. These are held by the Hon. Sec. in the 'JRA Library', and are available for postal loan. In recognition that postal rates can make such loans unattractive, he has begun digitising the books as pdfs, and two are now available - look for the blue links in Books > Our Library, where you will also find details of how to get books snail-mailed.
Another place to look for (and of course buy) is Amazon, and we're building up some suggestions. Go to Books > Our Amazon Booklists. If you've any suggestions for our Amazon lists, please make them here.
