### Welcome to the Library of Nicolaus Copernicus Astronomical Center

### How to find a book?

To find a book use the search form (simple or advanced). If there is only one item found, you will see its full record. In the holdings section look for 'call number' e.g. D2-48a - it is the shelving location of an item. In the library, prefix (e.g. D2) is printed on the bookcase edges and then on the shelves. It denotes topical section - for details please refer to our classification scheme below. For serials the call number is just the bookcase number followed by the shelf number (like B-1). The link next to the call number - "Browse Shelf" allows to browse among items sharing the same call numbers prefix (e.g. B2) - most of them are located physically on the same or neighbour shelf.

If search returns more than one item, you can select specific item by clicking on its title or check the line 'availablility' e.g.

Availability: Items available for loan: NCAC Warsaw [D2-48a] (4).means that there are 4 such items and the shelving location of first, available item is D2-48a.

### Basic information for patrons

- Books are located behind the glass wall to the left of the entrance (access only with a security tab)
- Serials are located downstairs (one of the doors to the right of the entrance accessible only with security tabs); serials can't be borrowed!
