📚 Literature Tools & Research Discovery

Finding, evaluating, and managing the research literature is a full-time meta-skill. This page covers the full pipeline from discovery to citation management.

1. Finding Papers

Primary Search Engines

Tool	Strengths	Best Used For
Semantic Scholar	AI-extracted TLDRs, influential citation detection, free API	Quick comprehension, citation impact analysis
Google Scholar	Broadest coverage, citation tracking, alerts	General search, h-index tracking
dblp	CS-specific, curated, zero duplicate entries	Finding all papers by an author in CS venues
arXiv	Preprints, immediate access, no paywall	Cutting-edge work before peer review
Papers With Code	Links papers to GitHub code + benchmark leaderboards	Finding reproducible ML implementations
ACM Digital Library	Authoritative source for ACM papers	Systems, HCI, programming languages
IEEE Xplore	Authoritative for IEEE papers	Networking, hardware, signal processing

Specialized Discovery Tools

Connected Papers — Visual force-directed graph of papers connected by co-citation. Explore a “galaxy” of related work from one seed paper.
ResearchRabbit — “Spotify for papers” — recommends related papers based on your collection. Free.
Litmaps — Timeline-based citation map showing how ideas evolved over time.
Inciteful — Finds the most important papers connecting two specific papers.
OpenReview — Access submitted and rejected papers with full reviewer comments at top ML venues.

2. Evaluating Venue Quality

Conference Rankings

CORE Rankings Portal is the standard for CS conference prestige:

Tier	Meaning	Examples
A*	Flagship, highest prestige	NeurIPS, ICML, CVPR, SOSP, SIGCOMM, PLDI
A	Excellent, highly competitive	ICCV, ECCV, USENIX ATC, EuroSys, OOPSLA
B	Good, solid venue	BMVC, Middleware, LCTES
C	Acceptable	Lower-tier venues

Journal Rankings

SCImago Journal Rank (SJR) — Eigenvector-based prestige ranking. Q1 = top 25%, Q4 = bottom 25%.
Clarivate JCR — Journal Impact Factor (JIF). Requires institutional access.
DOAJ (Directory of Open Access Journals) — Verify that a journal is legitimate open-access (not predatory).

Predatory Venue Detection

[!WARNING] Predatory conferences and journals accept papers for a fee with no real peer review. Publishing there can permanently damage your reputation.

Red flags for predatory venues:

Unsolicited email invitations with flattery
Acceptance promised within 24–48 hours
Article Processing Charges (APCs) revealed only after acceptance
No verifiable editorial board
URL variations of legitimate venue names (e.g., ieeexplore-conf.com)

Verification tools:

Think. Check. Submit. — Structured checklist for evaluating venues.
Beall’s List Archive — Historical record of known predatory publishers.
COPE (Committee on Publication Ethics) — Verify if a journal/publisher is COPE-compliant.

3. Reference Management

Zotero (Recommended)

Zotero is the gold standard for academic reference management. It is free, open-source, and deeply integrated with LaTeX.

Setup:

Install Zotero desktop app.
Install the Zotero browser connector (Chrome/Firefox).
Install Better BibTeX plugin for LaTeX integration.
Create collections for each project/topic.
Configure Better BibTeX citation key format: [auth:lower][year][title:skipwords:lower:select=1,1]

Power features:

Browser save: Click connector on any paper page — Zotero saves metadata and PDF automatically.
Auto-sync .bib file: Better BibTeX can auto-export a .bib file to your LaTeX project directory. It updates when you add papers.
PDF annotation: Annotate PDFs directly in Zotero; annotations are stored as notes.
Group libraries: Share a Zotero library with your lab group.

Alternative Reference Managers

Tool	Free Tier	LaTeX Integration	Cloud Sync	Best For
Zotero	300MB free	Excellent (Better BibTeX)	Yes	Most users
Mendeley	2GB free	Good	Yes	PDF annotation heavy users
JabRef	Unlimited	Native (BibTeX-native)	Manual	LaTeX purists
Paperpile	Paid ($3/mo student)	Good	Google Drive	Google Docs users
EndNote	Institutional	Good	Yes	Biomedical fields

4. Staying Current

Alert Systems

Set up automated alerts to stay current without spending hours searching:

# Google Scholar Alert
Go to scholar.google.com
Search your topic keywords
Click "Create alert" at the bottom of results
Set delivery frequency (weekly recommended)

arXiv RSS — Subscribe to cs.LG, cs.CV, cs.AI, cs.NI etc. in any RSS reader.
Semantic Scholar Research Feeds — AI-powered recommendations based on your reading history.
Twitter/X lists — Create a curated list of researchers in your area. They share important papers in real time.
HuggingFace Daily Papers — Curated list of the day’s most important ML preprints.

Reading Group Structure

A weekly lab reading group is the most efficient way to stay current as a team:

Role	Responsibility
Presenter	Selects and presents one paper (20 min talk + 10 min discussion)
Critic	Prepares 3 specific questions or criticisms in advance
Connector	Identifies how this paper connects to lab’s current projects
Moderator	Keeps time, ensures everyone contributes

Rotate roles each week. Record sessions if permitted.

5. Building a Literature Review

A systematic literature review for a thesis or survey paper requires a structured methodology:

PRISMA Flow (for systematic reviews)

Identification: N papers found via search
        ↓
Screening: Remove duplicates; apply title/abstract filter
        ↓
Eligibility: Apply full-text inclusion/exclusion criteria
        ↓
Included: Final set of papers for review

Tools for Systematic Reviews

Rayyan — Collaborative screening tool for systematic reviews. Free for academics.
Covidence — Cochrane’s systematic review platform. Institutional access often available.
Elicit — AI-powered literature review assistant. Extracts structured data from papers.
