The Society maintains a collection of books, reprints and periodicals housed within the library of the National Botanic Garden of Wales at Llanarthne near Carmarthen in Wales (see ). It contains about 6,000 items, including complete runs of the The Bulletin and The Lichenologist. Of especial interest are two first editions of books by Acharius, the Swedish ‘father of lichenology’.

The library is open all weekdays, but changes made as a result of Covid-19 mean that the Archive Room where the BLS library is situated is now the permanent workplace of a member of NBGW staff. If you intend to visit the library please contact the BLS librarian Theresa Greenaway at least a week beforehand so that an appointment can be made.

Most, but not all, the books and periodicals can be borrowed by members in return for an undertaking to return the item plus reimbursing the National Botanic Garden of Wales for the postal costs. The Lichens of Great Britain and Ireland will not normally be lent out as the postal costs would be close to the purchase price of the book, instead you are encouraged to purchase your own copy or arrange to borrow one locally.

Copies of reprints can be made by arrangement with the BLS librarian.


The majority of the Society’s archives are in the Library of the Royal Botanic Gardens Edinburgh (RGBE). All the original mapping cards, correspondence and other items are nowawaiting inventory work, so that they can be properly documented and made available more widely.
