The use of a library's collection should be monitored and the results should be taken into consideration in order to establish an effective and efficient collection development and collection management policy. This paper analyzes a total of 884,593document delivery requests submitted to the National Academic Network and Information Center ULAKBİM to identify a core journals collection, and to find out if there is a relationship between the frequency of use of a journal and its impactfactor and half-life obsolescence . A total of 127 core journals satisfied one third of all document delivery requests both remote and in-house requests . The number of core journals satisfying one third of all requests submitted to the Document Delivery Unit DDU and Reference Services Reading Room RDRR desk in-library use was 184 and 97, respectively, and 87 of which were com­mon. The mean half-life of all journals used in DDU was 10 years while it was 10.3 years for core journals only. The corresponding mean half-life for the same journals calculated on the basis of the number of citations taken from the Journal Citation Reports 2004 was 7.8 years. The mean half-life for all journals used in RDRR was 10 years while it was 7.6 years for core journals only. The corre­spondingcitation-based mean half-life was also 7.6 years. No statistically mean­ingful relationship was observed between the frequencies of use of core journals and their impact factors. Yet, a low but statistically significant relationship was observedbetween the use frequencies and total citation counts of RSRR core jour­nals Pearson's r = .280, p < .01 . Findings indicate that the frequencies of the local use of journals are more important than their impact factors and total citation countswhen developing and managing a journals collection

Bir kütüphanenin etkin bir koleksiyon geliştirme ve koleksiyon yönetimi politikasının olabilmesi için, koleksiyonun kullanımının izlenmesi ve izleme sonuçlarının politika oluştururken mutlaka dikkate alınması gerekmektedir. Bu çalışmanın amacı; Ulusal Akademik Ağ ve Bilgi Merkezi ULAKBİM Belge Sağlama Hizmetleri ve Okuyucu Salonu Referans Hizmetleri Birimine yapılan toplam 884.593 makale isteğini analiz edip ULAKBİM için “çekirdek dergi” koleksiyonu belirlemek ve dergi kullanım sıklıkları ile dergi etki faktörü ve yarı-yaşamı eskime arasındaki olası ilişkileri incelemektir. Tüm belge sağlama isteklerinin üçte biri 127 çekirdek dergiden sağlanmıştır. Belge Sağlama Hizmetleri Biriminde isteklerin üçte birinin sağlandığı çekirdek dergi sayısı 184, Okuyucu Salonu Referans Hizmetleri Biriminde ise 97’dir. İki Birimde de kullanılan or­tak çekirdek dergi sayısı 87’dir. Belge Sağlama Hizmetleri Biriminde kullanılan tüm dergiler için yarı-yaşam ortalaması 10 yıl, çekirdek dergiler için 10,3 yıl, Journal Citation Reports’tan 2004 alınan ve atıf sayısına göre hesaplanan yarı- yaşam ortalaması ise 7,8 yıldır. Okuyucu Salonu Referans Hizmetleri Biriminde kullanılan tüm dergiler için yarı-yaşam ortalaması 9 yıldır. Çekirdek dergiler için hem kullanım sayısına hem de atıf sayısına göre hesaplanan yarı-yaşam ortalaması 7,6 yıldır. Çekirdek dergilerin kullanım sıklığı ile etki faktörü arasında istatistiksel açıdan anlamlı bir ilişki yoktur. Okuyucu Salonu Referans Hizmetleri Biriminde kullanılan çekirdek dergilerin toplam atıf sayısı ile kullanımı arasında ise düşük ama istatistiksel açıdan anlamlı bir ilişki gözlenmiştir Pearson’s r = 0,280, p < 0,01 .Bulgular dergilerin yerel kullanım sayısının süreli yayın koleksiyon geliştirme ve yönetiminde etki faktörü ve atıf sayısından daha önemli olduğunu göstermekte­dir
