The Advanced Catalogue Search helps you find the right item from our catalogue of more than 100000 books, DVDs and equipment. Fill out one or more of the fields. The more keywords you use in your search, the more focussed your search result will be. To search for a book by ISBN, or to use our stock codes, please use the search form at the bottom of the advanced search page.

We list out-of-print items on our website so that you know if something you are searching for is no longer available new. Out-of-print titles are not available from NHBS. However, we have partnered with AbeBooks to enable you to find used copied of out-of-print books.

If the publisher decides to reissue an out-of-print title we will update the status on our website accordingly.

When browsing by subject or viewing search results on www.nhbs.com the items are arranged by order of popularity by default. You can change the order in which they are arranged by either 'Author', 'Title' or 'Publication Date'. You can re-sort your list of books at any time.

NHBS can source any in-print title for you regardless of the subject or language. Please contact Customer Services with the book title, author, ISBN or any information you have – we will find the title for you. So, if you saw a book in a library last year and only remember part of the title, or if your colleague showed you a field-guide which you are not sure of the name of, Customer Services will help you find the title.

To find a list of books on a specific subject use the Browse by Subject links e.g. Zoology. Click on a heading for the subject you are looking for and a new page will appear, which has a list of sub-headings. Again, click the sub-heading for the subject you would like to browse – our categories continue in this way creating an increasingly specific selection, e.g. to browse to Bats you would follow the route Zoology->Mammals->Bats(Chiroptera).

Every version of every publication listed by NHBS is assigned a unique stock number. This number appears on the title information pages of our website preceded by a # symbol. For titles which have been published in more than one version (e.g. a hardback and a paperback), a different stock number is assigned to each version to distinguish between them. You can quote NHBS stock numbers when ordering.

To search for a book by our stock number, please use the search form at the bottom of the advanced search page.

The International Standard Book Number (ISBN) is the international standard method of identifying a book. Every version of every book is given a unique ISBN by its publisher which allows it to be identified. For titles which have been published in more than one version (e.g. a hardback and a paperback), a different ISBN is given to each version to distinguish between them.

On January 1st 2007, ISBNs were increased in length from 10 digits to 13 digits in order to expand the numbering capacity of the ISBN system and overcome numbering shortages in certain areas of the world. As such, ISBN-13 has now succeeded ISBN-10.

NHBS show ISBN-13 on our website’s title information pages for books published in or after 2007, otherwise ISBN-10 is shown. However an ISBN-13 search can be performed for any book and either ISBN-10 or ISBN-13 can be quoted in correspondence with us.

We also list and sell books without ISBN numbers.

We have a large selection of DVDs, DVD-ROMs, CDs, CD-ROMs, VHSs, Maps and other print media.

NHBS also sells a growing range of Wildlife & Ecology Equipment
