In some cases, one might need to purchase a copy of a book for convenience or for wish to expand one’s library.
In all cases, for finding used books, I recommend firstly searching the book search engines as ordered below, then if it is not found, one can make enquiries or search the catalogues of other booksellers. It is also useful to pop in to one’s local used book shop (if one exists) and enquire about books of interest from time-to-time. If one has the time and means of travel to get there, Hay-on-Wye (see below) should be visited from time-to-time as many books which you may desire can be found there.
A number of booksellers have been very useful in my search for used books. I will list some recommended shops here at some point. In the interim, and for a fairly comprehensive list of booksellers in the UK, please see below. Some booksellers may offer a book acquisitions service. Some more specialised booksellers will send out catalogues or newsletters that are subject specific upon subscription.
The Book Guide was an invaluable source for where to find second-hand and antiquarian books in the UK. The site listed and described booksellers and provided a wealth of information about fairs, auctions and book care specialists. Sadly the site has closed, but supporters are seeking to resurrect some of the content:
The town of Hay-on-Wye, which is on the Welsh/English border, is referred to as the ‘used book capital of the world’ by some. A good number of booksellers can be found in the town, which attracts many visitors wishing to find books. Some of the bookshops specialise, whilst others are more general. There is undoubtedly a very large selection of books in the town, and a visit could be comparable to browsing though much of the book search results found on the internet. See http://www.hay-on-wye.co.uk/bookshops/ for more information and for links and contact details for the bookshops.
