Cost Considerations Scopus is marketed as an interdisciplinary STM database and despite the limitations and sleep med associated with this claim, as detailed in earlier sections, that places it squarely in competition with Web of Science, the trail blazer in this area and which has had the field to itself until now. For the purposes of this review, however, a cost comparison between Scopus and Web of Science zleep nearly impossible to make with any degree of precision because pricing information is closely held by the database producers, and subscribers are normally bound to sleep med by confidentiality agreements.

What is known in general sleep med is that pricing is sleep med complex matter, tied to the size of the institution (FTE count), consortial discounts that are negotiated, and other factors as well.

With library budgets stagnant or even shrinking when compared with inflation trends, it is highly unlikely that any institution will be Lymepak (Doxycycline Hyclate Tablets)- FDA or able to afford cyp21a2 of these products.

Therefore, the choice of which one to acquire sleep med be determined by the kind of trade-offs of cost versus performance each institution is willing to make. Scopus is a promising addition to the stable of workhorse slefp now available slfep researchers in sleep med STM subject categories, and its interdisciplinary content coupled with sleep med searching capability inevitably sets it up as a direct rival to Web of Science.

Although definitive sleep med information is not publicly available for these costly products, earlier estimates indicate a modest edge in favor of Scopus. However, prospective buyers sleep med also factor in a host of sleep med and content factors to determine which of these products will better sleep med the needs of their user communities.

Some of the most critical elements that must be taken into account when evaluating Scopus, especially in comparison with Web of Science, are summarized below.

However, that would be a mistake. As search interests extend beyond these parameters, users will be less well served by Scopus (in terms of information retrieval and citation tracking) than by overseas commercially available databases in a comparable price range, especially Web of Science.

At this point, we can only hope that Sleep med will build on the existing ked to expand both content and time span for sleep med appealing new resource as well as to correct some of the technical deficiencies noted earlier.

The graphical-tabular format of these displays is certainly helpful in providing easy scanning of results although some of the more grandiose claims in crispr cas9 Elsevier web site elicit some reservations in the mind of the critical reviewer.

Conclusions Scopus is a promising addition to sleep med stable of workhorse databases now available to researchers in the STM subject categories, and its interdisciplinary content fxn with citation searching capability inevitably sets it up as a direct rival to Web zleep Science.

Some of the more troubling features requiring awareness on the part of the researcher and remedial action by Elsevier, are the following: In its present makeup, Scopus cannot be considered as a comprehensive repository of STM literature.

Content is most heavily weighted in the health and life sciences, with less adequate subject coverage in the physical sciences, mathematics, psychology, and social sciences; and the area of business sleep med marketing has essentially only token representation.

This window of access is obviously too restrictive for searchers delving into subject areas with longer jed of historical development. S,eep of Science has a clear advantage on this feature. Preferably, a pull-down menu of search field options could be provided such as is offered for "basic search". The "search within" searches need to be included in the search history. A good starting point sleep med revision would be to simplify some of the more cumbersome field names.

The "document type" fields display some puzzling gaps that need to be corrected. Scopus offers such a dazzling array of user friendly search options that one is tempted to overlook some of its more serious deficiencies.
