There are many database for this purpose. We can suggest database based on users needs. But, generally scienedirect, Emerald, Ebsco are good for scholars.

Professionals in library services often use research databases due to their comprehensive coverage, authoritative content, and user-friendly interfaces. Here are some top-rated research database subscriptions: 1. Library, Information Science & Technology Abstracts (LISTA) 2. Library Literature & Information Science Full Text (LLISF) 3. ERIC (Education Resources Information Center) 4. Scopus 5. Web of Science 6. ProQuest Central 7. PubMed Each offers unique features and content coverage, so the choice of subscription may depend on specific research interests and institutional requirements.

No Brasil a principal base de dados é o oferecido pela Capes. O aplicativo .periódicos. permite ao usuário ter acesso ao acervo do Portal de Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), uma fundação do Ministério da Educação (MEC). É uma biblioteca virtual que disponibiliza conteúdo científico internacional de alto nível, com acesso a periódicos, referências bibliográficas com resumo, teses e dissertações, normas técnicas, livros, obras de referência, estatísticas, patentes, arquivos abertos e redes de e-prints. Mas o acesso é liberado apenas para instituições e pessoas cadastradas, não é de acesso livre.

There are a number of top rated research database subscriptions that library professionals can use for enhanced service. Such as EBSCO host, JSTOR, web of science, Scopus(Elsevier), ProQuest Central, IEEE Xplore etc.

Librarians are very much familiar about various research databases because of their scope of work. Mostly authenticity, reliability, impact factor of the publications, periodicity of updates, collection coverage are considered for validating most trust worthy databases. Here are some of my recommendations 1. EBSCOHost 2. EMIS- Emerging Market Insights 3. Market Line 4. getAbstract- Book Summaries 5. SCOPUS 6. IEEE Explore 7. Elsevier 8. Chemical Abstract 9. MedLine 10. SciFinder

LISTA, SCOPUS, WOS, EBSCO, SCIENCE DIRECT, EMERALD, PROQUEST, TAYLOR &FRANCIS, IFLA, ALA, SPRINGER, SAGE, WILEY, ACM, THOMSON REUTER, PRESS READER, LexisNexis, WESTLAW, PUBMED, CINAHL, Cochrane, BMJ, Google scholar and many open source databases such as DOAJ, ERIC etc.

The range of databases withing EBSCO and its ease of use makes it my top pick in general. Its easy to apply filters, search only the topic database you want, only peer reviewed etc. Its also easy to set up folders to save articles for bigger projects, and provides citations.

There is no way a database can be in the Must Have category with out best customer service. There should be multi channel support systems like- connecting over phone, online customer support, live chat available for the users for seeking any immediate support and a handy reference list of FAQs should be there as DIY approach to understand & quick resolution of the issue.

While it is important to consider cost as a factor for evaluating merit of a database, equal importance needs to be given to evaluate the quality of the content being published. Learners service like customization, personalization & alert services etc are very much important features need to be evaluated while calculating cost efficiency of the database.

Por experiência, sugiro selecionar assinaturas de banco de dados de pesquisa com foco em plataformas como o Portal de Periódicos da CAPES, ou SciELO. Essas opções oferecem uma ampla variedade de recursos, incluindo periódicos científicos, livros e fontes primárias.

For academic research in particular, EBSCO, JSTOR, and google scholar should cover most your bases. Other big institutions like the Smithsonian, National Archives, National Library of Medicine, Library of Congress will be reliable as well.
