Leeuwarden (Leovardiae), Joannes Seydel, 1776, folio (with four folded leave in each signatue), originally a full parchment binding, but it has been rebound and restored, so it now has a leather covered spine with the original parchment spine over it with the original handwritten title, with a goldtooled vignette on the front (lady justice with sword, scale and covered eyes) and the back (heraldic crest of Frisia with the two lions), and with leather strips as closures, later blank signature (including endpapers) + 271+98 pp + a later added signature with 16 blank pages + 6 original signatures with contemporary handwritten additions to the catalogue + one more later blank signature (including endpapers). The book has been rebound and restored, the repairs are clearly visible (the leather of the spine, paper strips to reinforce the folds of the signatures), the construction is solid, the printwork is beautiful with wide margins (with some hadwritten notes, contemporary and modern ones) and clear pages with little to no stains. Apart from the goldtooled vignettes on the binding, there is also a printer's mark on the titlepage depicting the Frisian heraldic crest again. This copy is from the private collection of Jelle Kaspersma and Alie Vinke Kampen (1 oktober 2009). Jelle Kaspersma (1948-2019) was a Frisian poet.l A catalogue of the library collection of the Frisian Court (Hof van Friesland 1499-1811). This special legal library could only be used by members of the Court. The bulk of this collection consisted of lawbooks but there were also theological, historical and literary works. A manuscript catalogue appeared in 1634. The library then contained around 450 works. The first printed catalogue appeared in 1668. The collection by then had grown to 870 works. In 1733 the second catalogue appeared (1031 works) and the present work of 1776, compiled by Simon Binkes and Johan van Idsinga as decreed by the court on 6 Mai 1774, is the third and last printed catalogue of the collection. Nowadays this collection is part of Tresoar (Leeuwarden).
