Pronalazak literature i pouzdanih izvora

There is plenty of bad literature. Good literature — relevant, recent, authoritative — requires a strategy. The difference between a student who spends 40 hours wandering around Google and one who gathers fifty quality sources in the same time isn't intelligence, it's approach.

In this guide we walk through three phases: where to search, how to filter, and how to organize what you find. We'll pay particular attention to distinguishing scholarly from semi-scholarly sources — an increasing problem in an age when Google's first page often shows content that looks academic but isn't.

1. Start from databases, not Google

Plain Google is great for a first introduction to a topic, but not for sources you'll cite. Academic databases are your first steps:

• Google Scholar — the most accessible, a good first step. Covers a broad range of sciences.
• Hrčak (hrcak.srce.hr) — the portal of Croatian scholarly and professional journals. Essential for work on Croatian topics.
• Web of Science — a top-tier database of scientific publications (access through your faculty).
• Scopus — an alternative to WoS, broader in some fields.
• JSTOR — a rich database for the humanities and social sciences.
• PubMed — medicine and health sciences.
• SSRN — social sciences, economics, law (preprints and published papers).
• ResearchGate — a social network for researchers, useful for contacting authors and accessing PDFs.
• Faculty repository — bachelor's, master's, and doctoral theses of previous students.

2. The keyword technique

A search for "social media marketing" will give you 5 million results. A search for "social media marketing" + Croatia + tourism sector will give relevant studies.

A good search strategy:

• Use quotation marks for exact phrases: "discourse analysis"
• Combine terms (AND, OR): marketing AND tourism
• Exclude what you don't want (NOT or minus): marketing -sales
• Try English terms, especially for international literature
• Look for synonyms and alternative expressions (e.g. "students" / "undergraduates" / "university students")
• Filter by date — you'll often want only the last 5-10 years

3. Recognize a quality source

Not every article is worth the same. The hierarchy of academic authority looks roughly like this:

Top-tier (cite without hesitation)

• Peer-reviewed articles in reputable international journals
• Monographs published by recognized academic publishers (Oxford, Cambridge, Sage, Routledge)
• Doctoral dissertations from recognized universities

Solid (with critical assessment)

• Articles in national scholarly journals (categories A1, A2 per the Ministry of Science)
• Conference proceedings
• Master's theses and reports from reputable institutions
• Statistical data from official institutions (national statistics offices, Eurostat, OECD)

Secondary (only for introductory parts or as illustration)

• Professional journals and articles in quality media
• Institutional websites (with caution and dating)
• Books for a general audience written by authorities in the field

Avoid

• Wikipedia (as a direct citation — as a starting point for further searching it can be useful)
• Blogs (unless they belong to a recognized authority)
• Online articles with no author and no date
• Predatory journals — predatory publishers who, for a fee, publish almost anything without real peer review

"To cite is to stand beside an author. Ask yourself: would I want to be seen advocating this idea with this citation?"

4. The "snowballing" technique

Once you find a few key articles, use them as a starting point:

• Backward — look at the reference lists of those articles and find their sources (you'll often find earlier key studies)
• Forward — look at who cited that article (Google Scholar offers a "Cited by" button) to find newer research

This method often reveals relevant authors that a keyword search wouldn't find.

5. Organize your literature from the start

The biggest mistake: reading articles, taking notes in Word, and later trying to assemble everything into a coherent text. A better method:

Reference management tools

• Zotero — free, open source, syncs across devices
• Mendeley — popular among students, has a social component
• EndNote — a professional tool, paid, often available through your faculty

All three tools allow you to:

• Save a PDF and its bibliographic data with one click
• Organize sources into folders by chapter
• Add notes and tags for each article
• Automatically generate a reference list in the desired style (APA, Chicago...)
• Insert citations directly into Word or Google Docs

A note-taking system

For each article, record (ideally in a tool):

• The author's main thesis in one sentence
• The methodology (type of research, sample)
• The main findings (3-5 points)
• 2-3 quotes you might use directly
• The connection to your topic — where it fits in your paper

6. When to stop?

Searching for literature can go on forever. Signs you have enough:

• New articles increasingly cite authors you've already found
• The same themes repeat across different papers
• You reach saturation — no more substantially new perspectives
• You cover all the key authors and key schools of thought in the field

In conclusion

Quality literature doesn't happen by chance. It comes from strategy — where you search, how you filter, and how you organize. Devote a week or two to systematic searching at the start, use a reference management tool, and your paper already stands firm before you've written the first sentence.

Bad literature is easy — copy the first ten Google results. Good literature requires discipline, but that discipline pays back many times over in the quality of your paper.
