PhDr. Vladimír Spáčil made available the unique collection of charters of fond Town Olomouc Archive, deposited in the State District Archive in Olomouc, in the form of abstract catalog. PhDr. Vladimír Spáčil intended to make the edition of seals, but the idea has just recently come to realization. The catalog of seals has gradually been created thanks to initiative of PhDr. Karl Müller, the director of the Regional Archives in Opava. A total of 2,528 seals will be divided into thematic groups, e.g. Rulers and Ruling Princes, Nobility, Towns, etc. The dividing of the seals will make the orientation in sigillographic material easier. There were demonstrated examples of individual groups and example of the abstract, which accompanies every seal, at the workshop. The researcher gains the basic information about the seal, the frequency and the picture of the seal, which is indispensable. Photographs will be available on the website of archive.
